Does it also happen for all users? On my instances it works just fine.

[raimund-schluessler]

Can you also please check the requests, especially the ones to the calendars?

No, strangely just for one useraccount. For the others it works fine.

How do I do that?

I have the same symptoms as the author. After upgrading tasks 0.12.0, all existing tasks do not appear. What should I do?

[raimund-schluessler]

How do I do that?

Also in the developer tools. In the console you should see a lot of requests to the server when you load the app. There should be one to <ServerAdress>/remote.php/dav/calendars/<user>/ which should return the calendars (as array).

Weirdly, the code https://github.com/nextcloud/tasks/blob/master/src/store/calendars.js#L434-L439 which gives the error hasn't been touched since 0.11.3

I am actually not quite sure what I am exactly looking for.
This is a request for the not working user:

and it seems that the browser doesn't make a request to the "aufgaben" calendar, which is the case for another user, that also has the "aufgaben" calendar and sees the tasks calendar...

[raimund-schluessler]

I might have an idea. Could you please try this build:
tasks.tar.gz

I noticed the same bug. The version of the calendar app is Ver. 2.0.2., Tasks Ver. 0.12.0
In the error log of my browser the following error is displayed:

TypeError: "e.shares is undefined"
    Fri uidToColor.js:101
    t calendars.js:274
    t calendars.js:263
vue.runtime.esm.js:1888:12
    VueJS 4

Downgrade to 0.11.3 version, the existing tasks will be displayed normally.

tasks.tar.gz

I've tried that but it still doesn't work...

[raimund-schluessler]

Still the same error? Did you clear the browser cache?

[szaimen]

Thanks! after clearing the browser cache it works but now it also shows a subscribed ical calendar, which shouldn't be the case imho, since it is not writeable (and also wasn't shown on 0.11.3)...

[szaimen]

And btw: the console is now full of these messages. So many haven't been there before:

Ok, then I will release v0.12.1 with the fix and we can discuss whether we should show subscribed calendars in a separate issue. Could you please open one @szaimen

These warnings are not critical and we already ship our own version with the app.

[raimund-schluessler]

The fix is in the appstore, should be visible soon. Let me know if there are still problems, besides #910.
